Hierarchical data collection network supporting packetized voice communications among wireless terminals and telephones

A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a system supporting voice communication via a packet network, the code sections executable by a processor for causing the processor to perform the operations comprising:

• receiving, via a conventional telephone switching network link, an indication of an incoming voice call;
• accepting, via the conventional telephone switching network link, a destination address;
• identifying a packet network address based upon the destination address;
• sending, via the packet network using the identified packet network address, a message requesting setup of the voice call;
• receiving, via the packet network, a message indicating call status;
• establishing voice communication between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is received;
• and
• refraining from establishing voice communication between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is not received.

A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a telephony device, the code sections executable by a processor for causing the processor to perform the operations comprising:

• sending a message requesting setup of a voice call to a communication system via a packet network, the message comprising a destination address and information to cause the communication system to, at least:
• send, via a conventional telephone switching network link, at least one signal based upon the destination address requesting setup of the voice call;
• receive, via the conventional telephone switching network link, at least one signal representing call status;
• establish communication of signals representative of voice between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is received;
• and
• refrain from establishing communication of signals representative of voice between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is not received.

A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a telephony device, the code sections executable by a processor for causing the processor to perform the operations comprising:

• receiving a message requesting setup of a voice call from a communication system via a packet network, the received message indicative of:
• the communication system receiving an indication of an incoming voice call and a destination address, and the communication system identifying a packet network address for the telephony device based upon the destination address;
• and
• sending a message indicating call status to the communication system via the packet network, the sent message to cause the communication system to:
• establish voice communication between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is received;
• and
• refrain from establishing voice communication between the packet network and the conventional telephone switching network link, if call status indicating establishment of a connection is not received.

A non-transitory computer-readable medium having stored thereon a computer program having a plurality of code sections for operating a communication terminal, the code sections executable by a processor for causing the processor to perform the operations comprising:

• sending, from the communication terminal via a packet network, a message requesting information for routing a voice call from the communication terminal to a telephony device of a convention telephone switching network via a second communication terminal of the packet network, the second communication terminal supporting voice communication between the packet network and a conventional telephone switching network;
• receiving, via the packet network, the routing information;
• initiating establishment of the voice call between the communication terminal of the packet network and the telephony device of the conventional telephone switching network, using the routing information;
• communicating signals representative of voice between the communication device and the telephony device via the packet network, the second communication terminal, and the conventional telephone switching network, if a voice call connection is successfully established;
• and
• signaling a user of the communication device, if a voice call connection between the communication device and the telephony device via the packet network, the second communication terminal, and the conventional telephone switching network, is not able to be established.
